Young people play the most important role in getting all the prejudice out of our society. You may be intentionally or unintentionally influenced by your family, but when you are aware of this, you can overcome it. Just be what you are, which is obviously a nice socially aware person. When you meet someone, try to allow all preconceived ideas to fall away. There are so many prejudices: race,religion,physical looks,weight,etc. When we narrow down our group of friends we remain narrow ourselves, because everyone has so much to teach us. Give yourself the chance to really get to know people from the inside out. And celebrate the differences! Don't allow your friends to put others down based on preconceived ideas without speaking up in a gentle way. And one more thing, don't be too hard on the older generation in your family. They learned what they are from those who came before them. Just introduce them to your friends of every physical type. The best to you!
